Frequently Asked Questions
What stacking height and pitch does the DF40C(2.0)-40DS-0.4V(51) provide, and how do those dimensions benefit thin device designs?
The connector specifies a 2.0 mm stacking height and 0.4 mm contact pitch. The 2.0 mm board separation keeps overall device thickness minimal, critical for smartphones and wearables, while the 0.4 mm pitch accommodates 40 positions across fewer than 9 mm of board width, delivering high signal density in area-constrained layouts.
For a compact IoT sensor node stacking a wireless module on a processor board, how many signals does this connector route and at what voltage level?
The DF40C(2.0)-40DS-0.4V(51) routes 40 signal or power pins simultaneously, supporting common 1.8 V and 3.3 V logic interfaces such as UART, SPI, I2C, and GPIO buses typical in IoT sensor nodes. This pin count is sufficient to carry a full peripheral bus, several analogue inputs, and dedicated power and ground rails in a single compact connector pair.
How does the DF40C(2.0)-40DS-0.4V(51) compare to 0.5 mm pitch alternatives when routing a 40-pin MIPI CSI or DSI camera interface?
At 0.4 mm pitch, the DF40C(2.0)-40DS-0.4V(51) saves approximately 4 mm of board length compared to a 40-position 0.5 mm pitch connector (16 mm vs 20 mm), which is meaningful in camera module assemblies where PCB area is shared with lens holders and shielding cans. The Hirose DF40 series is widely used in camera-to-processor board interfaces in smartphones and drone flight controllers.
